Abstract:
Zincblende semiconductors are materials used in electronics since decades. In the last years, these compounds have been revisited and studied in the context of topological insulators and semimetals. For example, a two-dimensional CdTe/HgTe/CdTe quantum-well is a prototypical topological insulator studied intensively since 2005. Thouless, Haldane and Kosterlitz were awarded this years Nobel prize in physics for their fundamental work, which finally led to the current immense interest in these materials.
